492. When several #s are inside
parenthesis, the exponent
outside the parentheses must be
distributed to all the #s within
(4y)^2 = ((4)^2)((y)^2) =
(4^2) * (y^2) = 16y^2 246b
504. y=mx+b where b is the y-
intercept (the point which
crosses the y-axis) m is the
slope of the line, and x & y are
the coordinates of some point
on that line 252b
546. ignor decimal points and multiply the

273b
574. 1)Pick numbers that make sense for the
variable in the problem 2)Find an answer
using those numbers to get the "target
answer" 3)plug your #s into the answer
choices to see which choice equals the
target answer
287b
576. 1)Start with choice "c" plug that
into the problem to see if it
works 2)If "c" is to small go
larger 3) if "c" is too big try
smaller 4)If you don't know try
them all
